Abstract (en)
[origin: DE10041887C1] To exchange an intermediate calender roller, in a calendar roller assembly with more than three rollers with a press plane pitched at a given angle to vertical, at least the rollers below the intermediate roller are lowered. The lower roller immediately under the intermediate roller forms a gap for maneuver and is lowered by an additional value expressed as: h=(r1?+r2)(1?-cos alpha ) where r1 is the radius of the intermediate roller, r2 the radius of the neighboring roller, and alpha is the angle. At the same time, the neighboring roller is given a side movement (s) expressed as: s=h\*tan alpha . The gaps between the rollers below the intermediate roller are set at 8-15 mm according to the maneuver gap. The rollers under the intermediate roller are moved on the press plane. The limit stops for the lower rollers are adjusted to select the intermediate roller, using nuts on spindles for the adjustment. An Independent claim is included for a calender roller assembly, with rollers (9-12) under an intermediate roller (8) for exchange, aligned on an angled press plane, to be lowered parallel to the press plane (P) for an intermediate roller (8) exchange. Preferred Features: The rollers (5-12) are mounted on levers with the possible exception of a top and bottom roller (3). The levers pivot on columns (2), with an adjustable limit stop for each lever. The limit stops are formed by nuts and spindles. A control unit operates an adjustment mechanism to set the limit stops.
